9 Claims.

- This invention relates to an adjustable door holder and door stop.

An object of the invention is to provide improved means for mechanically holding a door of the swingable type open to any desired extent to improve the ventilation of a room having a door opening with which the door cooperates.

A more specific object is to provide an improved arrangement means incorporated in a single device whereby the door may be mechanically held open to any desired extent, in combination with stop means forming a part of the same device whereby the door may be prevented from further opening when once selectively positioned.

The invention also marks an advance in the crowded art to which it pertains, in that it provides an improved means for setting a door in a more or less open position at a multiplicity of positions, in which the door is held either permanently or temporarily in the adjusted position, at the option of the operator.

Still another and more specific object is to'provide an improved combination of a toothed segment, securable in a horizontal position superjacent to a corner portion of a dooropening, in combination with manually adjustable means connected both to the door and said segment in a simplified more conveniently operable manner, so as to carry into effect the above stated advantages and features of invention.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawing, which illustrates a preferred embodiment of the invention,

Fig. 1 is a perspective view completely illustrating the device in its operative relation to a swingable door, a fragment of the door and of the wall adjacent to the door opening being included in the view.

Fig. 2 is a vertical section taken through the device as positioned in Fig. 1, the plane of section being alongside the door.

Fig. 3 is a fragmental plan showing a portion of the device on an enlarged scale, the view point for this figure being indicated by line 3-3 on Fig. 2.

Fig. 4 is a reproduction of a right hand portion of Fig. 2, the swingable arm being shown in Fig. 2 in an operative relation to the toothed segment, and being shown in Fig. 4 is an inoperative relation to said segment.

Referring in detail to the drawing, the device is shown in an operative relation to a door 1 supported by hinges 8 one of which is shown in Fig.

- segment, there being'also an aperture through the segment in vertical alinement with the aperture of said lip. Through these alined apertures extend a headed pin IS, a spiral compression spring It, being coiled around said pin between the under side of its head and the upper face of said lip.

A swingable door holding arm 20 is, anchored at one end to said pin l5, said arm being shown of the strap metal type and the pin l5 being diametrically slotted from its lowerend to a point adjacent to its upper end so as to have inserted into the slot thus provided the inner end portion of said arm 20, there being a pivot pin 2| extending through the pin athwart its slot to secure the arm in the slot as shown. By the arrangement just described, the arm 2!] is at times held by the spring 16 in its upper, locking position in relation to the segment H, as shown in Fig.2.

The outer end portion of the swingable strap iron arm 20 is shown provided with a beveled, downwardly widening, laterally directed flange 22, said flange having a foot portion 23, which is directed horizontally outward in relation with the arm 2'0. The said foot portion of the flange carries at its underside a convex projection 24 which at times is in a holding relation to the locking opening 25 in a plate 26 which, is fastened in a flatwise manner to the upper surface of the door 1. When the holding arm 2!] is in the locked relation to the segment i I as shown in Fig. 2 the projection 24, owing to the fact that it is in effect beveled at all sides, cooperates with the apertured plate 26, yieldingly to hold the door I in the more or less widely opened position to which set by the operator.

In addition to its end flange 22, the locking arm 20 has a vertical, internally projecting, stepped flange 21 which affords a locking shoulder 28 and above said locking shoulder a recess 29. Said'looking shoulder 28 is shown positioned to, at times, interengage with the selected adjacent teeth of the segment I l in order to hold the door open to the desired extent...

In addition to the already described parts the locking arm 20 has pivoted to it pendant stop fingers 33 and 34. The stop finger 33 is pivoted at 35 to the upper part of the outer end portion of the arm at the side thereof opposite to the arm's flange 22, said finger when in a vertically pendant position contacting the inner side of the foot portion 23 of the arm 20, said foot portion being slightly extended laterally to be engaged by said finger 33. Said finger, in its pendant position, extends down below the upper edge of the door at all times to perform a stop function. The aforesaid finger 34 is of the angular character shown in Fig. 3, and is shown secured swingably to that side of arm 20 which isopposite to finger 33, the pivot pin 35 being common to both of these fingers.

Because of the manner in which the segmental plate H is centrally attached to the wall by means of its flange l2, each end portion of the straight side of said plate is spaced away from the wall the thickness of said flange. Room is thus provided at one side of the plate for the aforesaid finger 33 to be swung backwardly behind the plate, thus locking the swingable arm 20 (at this time disengaged from the door) in a inoperative position. In the case of doors hinged at the opposite side of the door opening the angular finger 34 is similarly used to lock said arm 20 at theopposite limit of its swing. The fingers 33 and 34 will necessarily be mounted under a sufficient pressure frictionally to main,- tain them in their upswung positions behind the segment ll when said fingers are so adjusted.

Owing to the fact that the flange 22 of the door holding structure at the free end of the swingable arm 20 is laterally directed, the finger 34 is made with a bend 34b thus offsetting its free end portion in such a manner as to compensate for the out-spacing of this finger from the wall when the segment is attached to the wall in the relation to the door opening shown in Fig. 1.
